BOLD signals of episodic memory retrieval in the hippocampus and neocortex

Functional neuroimaging studies have demonstrated activation of the brain's medial temporal lobe during episodic memory retrieval. However, inconsistent evidence from lesion studies indicate that, although the medial temporal lobe is essential for acquiring new declarative memories, it may not be critical for all forms of retrieval. Given the multitude of mnemonic and non- mnemonic processes invoked during a guided retrieval episode, including...
